Abstract
An improved windshield wiper blade of the type having two rubber elements forming parallel wiping edges. The elements are mounted in a rigid flexor which extends the length of the blade. Each element includes a hinge which permits the portion of the element including the wiping edge to flip over when the wiping direction is reversed. Each element further includes bumpers above and below the hinge only on the side mounted to face the other element. As the wiper blade is moved, the bumpers on only the leading element abut to establish the angle of the leading wiping edge relative to the windshield. The exposed side of each element is smooth and the bumpers are enclosed to prevent buildup of ice, snow or mud on the wiper blade.
